TB203 Guidance Update

The update relates to the testing and maintenance of fire pumps, which are a critical component of any sprinkler system. Under the revised guidance, there is now an expectation that fire pumps must be supervised by a trained and competent individual whenever they are in operation during testing.

What Has Changed?

Previously, it was common practice for electric fire pumps to be tested without the need for active supervision, particularly during routine service visits. However, the updated TB203 guidance states that:

"All fire pumps – whether diesel or electric – must be monitored from a safe location during operation."

This change aims to improve safety, reduce the risk of pump failure, and ensure that any issues are promptly addressed by someone who is capable of taking the correct action.

What This Means for Your Site

Depending on how your sprinkler system is managed and maintained, this new guidance may require a change in your testing procedures. Here's what you need to consider:

If A&F Sprinklers carry out your fire pump testing:

• A second engineer may be required to monitor the fire pump throughout the duration of the test.
• Alternatively, you may assign a trained and competent member of your own team to oversee the pump while our engineer completes the test.

This service will incur an additional charge if an extra A&F operative is needed. Our Service Sales Team will be in contact to review your current setup and offer tailored solutions.

If you conduct your own weekly testing:

• The same supervision requirements apply.
• Your on-site team must include someone who is trained and deemed competent to monitor the fire pump during each weekly test.

If you’re unsure whether your team meets these requirements, we can provide staff training to help bring your personnel up to the necessary standard.

If your equipment is located in the same plant room:

• In many cases, if the fire pumps and alarm valves are in the same space, a single trained person may be able to manage the testing duties.
• Our team can assess your site and advise on the most efficient and compliant way forward.
